CUHK's official language is chinese, so it's more like a typical chinese university. i mean, there are many things that arent written in english. OOHH some students couldnt talk to me in english... I didn't like the campus very much, but my parents did :-0
UST is on the mountain.... very high. The campus is fascinating- library, gym, mcdonalds and all that stuff. can see beautiful "ClearWaterBay" from domitory building i guess.. there is a bus stop at the univ but I dont think non goes to downtown(tism sha tsui) i think it's the right place to be isolated.. no offence! hmm, l personally prefer UST than CUHK but my parents said that UST doesn't look like a university. haha.
HKU is more lively and active, as I mentioned. Campus is small and it's in the middle of the road. duh. I could see many society posters and job recruitment posters. During lunch, a forum about city development something was going on..
I had lunch at CUHK and HKU cafeteria :-) both cheap and yummmmmy!!!
In short, i guess
campus size: CUHK > HKUST > HKU
intl students: HKU >>> HKUST> CUHK
food (

): CUHK> HKU
location: HKU > HKUST> CUHK
to be really honest, i was quite disappointed with all three univ.. there are just a few intl students at schools, and I heard that most of them are exchange students. also, HK was way too small and narrow to me

too high buildings with too many people... well I understand that it's not famous for the space. but it's a definitely coool city to have fun!!!
i can speak mandarin- it was easier for me to communicate with old people, shop assistants and bus/taxi drivers in mandarin than english. some was not able to speak english while some spoke english that i couldnt understand.. but generally, there was no problem when asking/talking.
@Muntasir
thx

well, my predicted grades were AAA, but I remember that I wasn't required to submit my predicted grades to HKU.
Anyways, my conditional offers are... *no scholarship, phew-
HKU - ABB without interview
HKUST - AAB with interview
CUHK - AAA without interview
Hope this helps :-)
